The PAD protesters or the yellow-shirted people officially started their protest at Sanam Luang in the center of capital Bangkok from 04:00 p.m. local time.

The rally was occurring after Thailand and Cambodia have downgraded their diplomatic relations due to conflict over an appointment of Thaksin as an economic advisor to Cambodia's government and Hun Sen on Nov. 4.

A day after the appointment of Thaksin, the Cambodian government announced recall of its ambassador to Thailand in a move to respond to the Thai government's recall of its ambassador to Cambodia.
